Thread: Looking for advice from anyone with tool making experience

Before I go about town talking to engineering shops, I'll ask on here first..

If I wanted to have a lathe grooving/cutting tool reshaped with a different angle or shape, what kind of engineering shop should I be looking for? (No I'm not going to do it myself with a file)
Are there specialists I can mail my specs to have it done?
As an example, if I wanted a small cutting tool thats shaped the same as a particular cartridge rim and extractor groove to modify parent cases for case conversions.
